  Hello Anubhav,

  Configuration seems fine.

  You need to set radius server as below

  RADIUS-server host x.x.x.x (where x.x.x.x is authetication radius server)

  RADIUS-server key (shared key used between AEC and device)

  You may also use order form below if you have several L3 interface on your device to specify which interface would be to use the RADIUS traffic.

  property intellectual Ganymede source x.x.x.x interface (this should the interface you have on your GBA as a aaa client)

  Hope that helps.

• AAA authentication for external router through PIX 515

  I have been in vain, to get the authentication AAA works to my external router, through the PIX.

  When I connect the router directly within that network (bypassing the PIX) AAA works fine, so I know the configuration of the AAA works between the router and the ACS server.

  Initially, I got the PIX configured with a static map between a global external address 192.x.x.12 and a 10.200.1.187 for the ACS server local address, but that didn't work either. So, currently I am using NAT exemption for the ACS server, but it does not work either.

  If I activate the debug on the PIX package, I see the ACS authentication request and response between the router and GBA when I try to connect to the router, but it is not successful. After the three way TCP handshake, the router repeats it is last receipt, and then the ACS asked an RST.

  The attached diagram shows the simple connection that I'm trying to create.

  The configuration of the PIX is also attached. (too large messages size):

  Thanks in advance for your help. I tried EAC for two days and have not found solutions that look like this.

  Ron Buchalski

  What to do is:

  1 PIX:

  -static map the ACS/GANYMEDE to a public IP address

  static (inside, outside) x.x.x.10 10.1.1.25 netmask 255.255.255.255

  -otherwise, if you have enough public IP, use the port forwarding for card IP ACS to PIX outside IP of the interface, IE x.x.x.2, via a specific TCP 49:

  public static tcp (indoor, outdoor) interface 49 10.1.1.25 49 netmask 255.255.255.255

  * allow ACS talk to external router via public IP

  Create/add entry for ACL applied to the outside interface to allow the GANYMEDE Protocol + switch router external to the ACS:

  access outside permit tcp host XXX1 host x.x.x.10 eq 49 list (Ganymede + use tcp 49)

  outside access-group in external interface

  * x.x.x.1 = outside the router

  2 ACS

  -Add the outside router IP (FastEthernet face PIX outside interface) interface as a client of the AAA

  -Making of course secret key is identical at ACS and router

  3. the outside router

  -Add the ACS as radius-server using its IP public, as mapped in PIX which is x.x.x.10.

  -check the key AAA statement is accurate.

  The test without saving the config is outside the router. Save ok once confirmed.

  I have similar facility before, and it worked very well.

• RADIUS authentication for the switch using ISE

  Hi guys,.

  Someone did he do Radius Authentication for switch cli connection using ISE?

  We did it in our environment with ISE, but it is a challenge to give read-only access / Priv-1.

  If some users know the enable password, they can use and earn full privilege.

  Anyway to get around this other than to change the enable password?

  We have thousands of switches and won't change on each of them.

  If you have another method please advice.

  Thank you in advance.

  Well, you can set the "enable" function also be controlled via the AAA server with the following command:

  AAA authentication enable... This way server AAA will be checked for authentication for the secret to activate and use the local database as a last resort

  I hope this helps!

• Test command of the AAA for EAP - TLS authentication for wireless users

  Hi all

  Can anyone suggest me the test command to verify the eap - tls authentication for the Cisco WAP's wireless.

  If it's an authetication jump we can use the command to test the connection below

  Radius of group aaa Testwap-01 #test [email protected] / * / o4 & yJ) NoL$ new-code %0
  Trying to authenticate with the server radius group
  User successfully authenticated

  But eap - tls is not delivered with the password. He insists that for the user name.

  We strive for remote location then test remotely before production.

  If someone help pls in that if we have a command to test or debug command to test this authentication.

  EAP - TLS requires a client certificate. How can you have a simple command that analysis without loading any certificate on the router/switch? It does not exist. This is why eap - tls is not considered an easy to deploy eap method: because it can go wrong on several levels.

  The aaa command test performs a PAP authentication, therefore, it tests the connectivity of the base RADIUS and name of user and password.

  If it works, the only thing that can break for eap - tls are certificates, as well as the radius server will be able to tell if something worng.

• AAA RADIUS authentication for the only user group

  Hello

  I use ACS3.1 and tries to use authentication radius for all network switches in my company.

  Meet the im problem now is how to restrict only a user group to access the connection/exec switches? It seems that all user IDS in my acs able to telnet (user access) to the switch (using their login credentials).

  I would like to limit still from telnet by using their ID except administrator group.

  Counsel on how this is possible.

  TKS!

  The GBA, you need admin users in their own ACS group separated, leaving other users in their own group also.

  Change the group that contains the users you don't want to give access to and under the heading of restricted access network (OAN), in "Group defined Network Access Restrictions", check the "Define based on IP access restrictions", choose "Rejected the call point" and enter switches in the table below (put a * in the port and address).

  This prevents standard users authentication to switches. You can add all your switches in a group of network devices (NDG) to this, then you have to add that, in the section NAR rather than adding each switch individually.

• The AAA authentication configuration

  We have ACS server 3.1 to AAA for authentication for all routers and switches. I want each person to connect the router using its own id, password password and activate. If the ACS server is unavailable, I want to have different id, password and enable password for console and telnet access. What is the right way to do this? I also want to follow all orders entered on the router.

  That's what I have:

  AAA new-model

  Please advise, thank you. its urgent

  To approach the issue from a slightly different angle - your original set of commands instruct the router to send the application for leave to GANYMEDE for each command to level 15, which includes see the race. Your GANYMEDE server was not configured to allow your use to see the race and if your attempt to show performance was rejected.

  Your revised set of orders doesn't send application to GANYMEDE for level 15 commands (or other classes of orders by the way) and so there is no question here to see the race.

  As far as I can say that your revised set of orders do not permit for orders. You can achieve this result just as easily (and with fewer complications in your configuration) If you delete just aaa authorization command from your config lines.

• GANYMEDE + Queueing AAA authentication

  Hello

  I've recently updated the IOS on my 3560 X 15.0 (2) SE3 and I can't get GANYMEDE works correctly. It worked properly on this device until I updated the IOS so I don't know what happened. I've made a few other changes as well (management IP change and clean the other config) so I'm not 100% sure what the issue was with the IOS. I have this same exact config on several other Cisco devices and it works fine. Any thoughts are appreciated.

  Config:

  AAA authorization exec default group Ganymede + local

• AAA authentication sequence

  We have following commands configured on the 2950

  AAA new-model

  AAA authentication login default local radius group

  the AAA authentication enable default

  RADIUS group AAA authorization exec default authenticated if

  localuser username secret 5 *.

  When you try to access the switch it's mark to the RADIUS server, but it is not authenticated.

  And then he gets authenticated with the local user name.

  Here is the log of the RADIUS server

  It shows the correct user name and correct the source of the switch IP address.

  Authentication provider = Windows

  Authentication server =

  Policy-Name =

  Authentication type PAP =

  EAP-Type =

  Code motif = 16

  Reason = authentication was not successful because an unknown user or bad password name has been used.

  In principle it was expected that as long as the switch is able to connect to the RADIUS server, it will not use the local username for authentication.

  But the switch uses the local username even if he can contact the RADIUS service.

  Please share the experience.

  Thank you

  Hello

  Indeed, I've recreated the issue when authenticating against a RAQ. My switch is running a newer version, however, it always reports the error of decryption on newspapers when the shared secret is incorrect. Shared secret configured as "cisco" on the switch and as "cisco123" relating to the registration of the IAS RADIUS client. Got the following text:

  Priv15 of the user has been denied access.

  Fully-qualified-user name = CAMEJIA\priv15

  NAS-IP-Address = x.x.250.12

  NAS-identify =

  NAS-Port =

  Proxy-policy-Name = use Windows authentication for all users

  Authentication provider = Windows

  Authentication server =

  Please, create a new RADIUS client for the switch only and use a single key as "cisco" on both sides. Do not forget that we should not hit the space bar when you configure the key on the IOS since it will space as a valid shared key figure.

  I hope this helps.

• banner of AAA authentication

  I have configured the banner authentication aaa and aaa fail message on a router running 12.1 (15) - authentication is done by ACS 3.0.2 which works very well.

  Problem - the banner of authentication does not appear (nothing is outside of "username:"-don't not even 'check' user access) If you enter a wrong password, but the failure message. If I console in and unplug the interface while the two messages very well.

  Workaround solution - if I set up a connection "banner" then everything works fine too, but I can't work out why does not display the "banner of aaa authentication."

  I suspect ACS prevents the message, but I can't work out how - can anyone suggest a solution?

  Thank you very much!

  By the way that the command "radius-server administration '? It doesn't seem to be documented, and it has no effect or not.

  The banner command does not work if you make the RADIUS authentication, it will not work if you do a RADIUS/local/etc. This is normal, cause with Ganymede you can have the sending server banner and guests down (even if with all I don't think that you can do) and so if you have configured authentication GANYMEDE the router does not take into account the banner command and waits to see if she gets a new one from the server RADIUS itself. If it is not it will simply display the usual guests.

  As for the 'radius-server admin' command, honestly, I have no idea, never seen anyone use. Online help says "start the daemon of Ganymede management administrative messages", but what really I don't know, maybe someone else can help.

  Paul

  What you want to do for authentication if the RADIUS server is down? For telnet and console access you can use the line as a backup method because it is possible to configure a password for the line on the console and vty ports. Which type of backup method you want for HTTP? The one that seems most logical to me would be to a local authentication in order to cover the situation where the server is down.

  To use local authentication, you must do the following:

  -create a definition of the local user (maybe more if you need extended security).

  -specify a special method for authentication of the aaa.

  -specify that http, using the special method.

  The configuration might look like this:

  password user tech1 tech1

  AAA authentication login http_auth group Ganymede + local

  IP http authentication aaa - authentication of the connection http_auth

  Or you can decide to use the secret to activate (or password that is configured in office). The config might look like this:

  AAA authentication login http_auth group Ganymede + activate

  IP http authentication aaa - authentication of the connection http_auth

  If you want a different backup method, let us know what it is and we'll see how it could be implemented.

• Disable authentication for reverse Telnet over Async lines

  I have a 2811 which behaves as a server terminal server with several line async being used to access the console.
